Benign Prostatic
Hyperplasia (BPH)

and BOO (Bladder Outlet Obstruction)

This page was created for patients who suffer from BPH and are searching for minimally invasive treatment options, as alternatives to the existing surgical treatments. The information provided on this page will help you and your loved ones to learn more about the condition, the causes and effective treatment options.

Patient
Information

What is BPH (Benign Prostatic Hyperplasia)?

BPH is an enlarged prostate gland. The prostate gland surrounds the urethra, which is the passage between the bladder and the end of the male penis. this passage facilitates the flow of urine out of the body. Since the prostate gets larger as men age, the Urethra gets partially squeeze or blocked, thus causing difficulties urinating and emptying the bladder.

BPH will occur in almost all the male population as they age. Although it is a chronic and progressive condition that causes various levels of discomfort (based on the stage and level of prostate enlargement), it is not a life-threatening condition such as cancer
and prostatic cancer.

What are the causes?

Benign prostatic hyperplasia is caused by the aging process in men. Hormone balance changes as Men age, facilitating unbalanced prostatic cell growth resulting in an enlarged prostate, blocking the urethra.

What could be the symptoms?

  • Frequent toilet visits during the day as well as during the night
  • A feeling of unemptied bladder following urination
  • Weak urine stream
  • Decreased urine output
  • In extreme and more advanced cases of BPH the prostate may fully occlude the urethra, which could lead to full urinary retention, i.e. the bladder cannot empty. This can cause infection, stone formation as well as severe kidney damage.

Surgical Treatment options;

The surgical treatment options include various methods of either cutting or ablating the inner part of the urethra using a form of energy to cut the tissue

TUR (Trans Urethra Resection) is the most common procedure where an electric loop is inserted and will cut the tissue away until a large enough lumen has been created and urine can flow.

New forms of cutting methods are being used today. Various forms of lasers technologies are being used to cut the tissue away and clear the lumen.

TUNA (Transurethral Needle Ablation) treatment and TUMT (Transurethral Microwave thermotherapy) are also methods of ablating, and/or easing the symptoms of BPH.

Risks involved with surgical treatments:

All surgical treatments have a higher risk of post OP complications depending on the form of procedure performed and surgeon’s proficiency.

Among them are:

  • Post OP pain
  • Bleeding
  • Various urine Incontinence levels and duration
  • Erectile dysfunction due to nerve damage
  • Retrograde ejaculation
  • Urethra stricture
  • Urinary tract infections

Today new minimally invasive methods are used more frequently due to the lower risk of complications. Among them are the new generation of polymeric stents and their advantages for various applications in the urinary tract.

What is a Stent?

A stent is a “tube” inserted into a natural passage in the body, in order to temporarily or long term hold such a natural conduit open, and facilitate urine free flow.

The new generation of the Allium Triangular Prostatic stents have a unique anatomical adaptive design (i.e. they are designed to fit the anatomy), they have a unique coating that prevents possible in-growth of tissue, and reduce encrustation rates. They also have a soft segment to allow proper sphincter functionality, thus not disturbing the anatomical functionality in the prostatic urethra.

Why are Urethral stents inserted?

Urethral Stents are inserted in cases of Bladder Outlet Obstruction (BOO), where BPH is one of the indications. An additional advantage of a stent insertion into the prostate is the fact that a stent is a reversible procedure! It can always be easily retrieved if needed, unlike invasive methods.

How are stents inserted?

Implantation of a urological stent is simple and is usually performed under a local or regional anesthesia. Unlike surgical treatments, in most cases it is not necessary to use full anesthesia in order to implant a stent. The surgeon will need to pass the delivery system, which carries the stent to the designated location along the prostatic Urethra and use X-ray control to ensure that the stent is correctly positioned.
Once in the right place, the surgeon will deploy the stent and it will immediately expand and support an open passage for urine flow through the prostatic urethra.
The procedure takes approximately 15- 30 minutes to perform.

What will I have to do prior the procedure?

  • You need to sign a consent form for this procedure
  • You will be admitted to the Day Surgery Unit and stay in the hospital overnight. In some countries patients are released home the same day.

Are there any complications?

In most cases the placing of a Prostatic stent will be problem free. In some cases patients could experience transient pain, possible discomfort, mild hematuria, or Post Op infection (not related to the stent).

In cases where symptoms continue for a prolonged period of time and the patients choose so, the stent can then be easily removed by the physician without any complications.

What should I expect afterwards?

  • Immediate relief
  • Free urine flow

The advantages of using a stent; a minimal invasive and reversible method:

Full clinical adaptability

  • A site- specific stent that fits the anatomy and functionality of the Urethra
  • Extremely flexible for excellent comfort
  • Special anti-reflux geometry

No tissue ingrowth & significant reduction of the rates for stone formation and calcification

  • Stents are 100% covered with a thin polymeric layer
  • Designed for a long indwelling time

Easy placement and simple removal

  • Inserted under vision or fluoroscopy
  • Simple & non-traumatic unraveling mechanism
  • Designed with a unique anchoring mechanism to prevent migration

How is the stent removed?

Easy and Safe Removal - stent is retrieved by simply pulling it
out with a small surgical grasper.
